Compress PDF
Shrink file size by re-rendering each page as a compressed image. Best for scanned or image-heavy PDFs — text will no longer be selectable afterward.
Frequently asked questions
Will compressing my PDF reduce the quality?
It can, depending on the compression level you choose. "High quality" keeps images closer to their original resolution, while "Smallest size" applies more aggressive compression that may visibly reduce image sharpness.
Does compressing a PDF remove selectable text?
Yes — compression re-renders each page as a compressed image, so it's best for scanned or image-heavy documents. Text in the compressed file will no longer be selectable or searchable.
Is there a file size limit for compressing PDFs online?
No hard limit — but very large files depend on your device's available memory, since everything is processed locally in your browser.
Is my PDF uploaded to a server when I compress it?
No. Compression happens entirely on your device — the file is never sent over the network.
